Data Models in DBMS

A Data Model in Database Management System (DBMS) is the concept of tools that are developed to summarize the description of the database. Data Models provide us with a transparent picture of data which helps us in creating an actual database. It shows us from the design of the data to its proper implementation of data. Types of Relational ModelsC

Difference between File System and DBMS

The file system is basically a way of arranging the files in a storage medium like a hard disk. The file system organizes the files and helps in the retrieval of files when they are required. File systems consist of different files which are grouped into directories. The directories further contain other folders and files. The file system performs

Difference between Process and Thread

Process and threads are the basic components in OS. Process is the program under execution whereas the thread is part of process. Threads of a process can be used when same process is required multiple times. A process can consists of multiple threads. In this article we will explore difference between process and thread in detail. What is Process?

Functions of Operating System

An Operating System acts as a communication bridge (interface) between the user and computer hardware. The purpose of an operating system is to provide a platform on which a user can execute programs conveniently and efficiently. An operating system is a piece of software that manages the allocation of Computer Hardware. The coordination of the har

Difference Between IPv4 and IPv6

The address through which any computer communicates with our computer is simply called an Internet Protocol Address or IP address. For example, if we want to load a web page or download something, we require the address to deliver that particular file or webpage. That address is called an IP Address. There are two versions of IP: IPv4 and IPv6. IP

Differences between TCP and UDP

Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) both are protocols of the Transport Layer Protocols. TCP is a connection-oriented protocol whereas UDP is a part of the Internet Protocol suite, referred to as the UDP/IP suite. Unlike TCP, it is an unreliable and connectionless protocol. In this article, we will discuss the diffe

Types of Operating Systems

An Operating System performs all the basic tasks like managing files, processes, and memory. Thus operating system acts as the manager of all the resources, i.e. resource manager. Thus, the operating system becomes an interface between the user and the machine. It is one of the most required software that is present in the device. Operating System

Types of Transmission Media

Transmission media refer to the physical pathways through which data is transmitted from one device to another within a network. These pathways can be wired or wireless. The choice of medium depends on factors like distance, speed, and interference. In this article, we will discuss the transmission media. What is Transmission Media?A transmission m

The TCP/IP model is a fundamental framework for computer networking. It stands for Transmission Control Protocol/Internet Protocol, which are the core protocols of the Internet. This model defines how data is transmitted over networks, ensuring reliable communication between devices. It consists of four layers: the Link Layer, the Internet Layer, t

Semaphores in Process Synchronization

Semaphores are a tool used in computer science to help manage how different processes (or programs) share resources, like memory or data, without causing conflicts. A semaphore is a special kind of synchronization data that can be used only through specific synchronization primitives. Semaphores are used to implement critical sections, which are re

What is OSI Model? - Layers of OSI Model

OSI stands for Open Systems Interconnection, where open stands to say non-proprietary. It is a 7-layer architecture with each layer having specific functionality to perform. All these 7 layers work collaboratively to transmit the data from one person to another across the globe. The OSI reference model was developed by ISO - 'International Organiza

Types of Network Topology

Network topology refers to the arrangement of different elements like nodes, links, and devices in a computer network. It defines how these components are connected and interact with each other. Understanding various types of network topologies helps in designing efficient and robust networks. Common types include bus, star, ring, mesh, and tree to

Types of Keys in Relational Model (Candidate, Super, Primary, Alternate and Foreign)

Keys are one of the basic requirements of a relational database model. It is widely used to identify the tuples(rows) uniquely in the table. We also use keys to set up relations amongst various columns and tables of a relational database.

DBMS Architecture 1-level, 2-Level, 3-Level

A Database stores a lot of critical information to access data quickly and securely. Hence it is important to select the correct architecture for efficient data management. DBMS Architecture helps users to get their requests done while connecting to the database. We choose database architecture depending on several factors like the size of the data

ACID Properties in DBMS

A transaction is a single logical unit of work that accesses and possibly modifies the contents of a database. Transactions access data using read and write operations. In order to maintain consistency in a database, before and after the transaction, certain properties are followed. These are called ACID properties. For those looking to master thes

Caesar Cipher in Cryptography

The Caesar Cipher is one of the simplest and oldest methods of encrypting messages, named after Julius Caesar, who reportedly used it to protect his military communications. This technique involves shifting the letters of the alphabet by a fixed number of places. For example, with a shift of three, the letter 'A' becomes 'D', 'B' becomes 'E', and s

Introduction of ER Model

Peter Chen developed the ER diagram in 1976. The ER model was created to provide a simple and understandable model for representing the structure and logic of databases. It has since evolved into variations such as the Enhanced ER Model and the Object Relationship Model The Entity Relational Model is a model for identifying entities to be represent

Normal Forms in DBMS

Normalization is the process of minimizing redundancy from a relation or set of relations. Redundancy in relation may cause insertion, deletion, and update anomalies. So, it helps to minimize the redundancy in relations. Normal forms are used to eliminate or reduce redundancy in database tables. Normalization of DBMSIn database management systems (

Network Devices (Hub, Repeater, Bridge, Switch, Router, Gateways and Brouter)

Network Devices: Network devices, also known as networking hardware, are physical devices that allow hardware on a computer network to communicate and interact with one another. For example Repeater, Hub, Bridge, Switch, Routers, Gateway, Brouter, and NIC, etc. 1. Repeater - A repeater operates at the physical layer. Its job is to amplifies (i.e.,
